3 Clm'ms. (Cl. 189-72) This invention relates to an improved window frame assembly.

It is embodied in a window frame which is preferably formed of sheet metal structural parts and in an assembly embodying a group of prime windows wherein a sash is supported for slidable movement between complementary jamb portions of the window frame. One of these jamb portions is provided with a strip extending therealong and provided with a series of vertically spaced apertures. The sash which is slidably supported within the frame is provided with a latch bolt mounted thereupon for reciprocation toward and away from said strip and into and out of the apertures through the strip to releasably support thesash at vertically adjusted positions.

hired States Patent An object of the invention is to provide a construction 0f the character described wherein the jamb assembly at one side of the window frame is provided with a sash sealer strip extending therealong and tensioned inwardly away from the jamb face to bear yieldingly against the adjacent edge of the slidable sash and form a seal therewith and which jamb sealer strip is provided with vertically spaced apertures adapted to receive a reciprocable latch bolt carried by the sash to support the sash at adjusted positions.

Another object is the provision of a window frame assembly embodying complementary jamb portions and a sash slidably supported therebetween and wherein the sash is provided with a latch bolt reciprocable toward and away from one jamb portion and such jamb portion is provided with a series of vertically spaced apertures adapted to receive the latch bolt to support the sash.

A further object is the provision of a window frame assembly comprising a sill, a header, and opposed jamb portions which jamb portions are formed of sheet metal and channel-shaped in cross section with the bottoms of the channels disposed parallel to the plane of the window opening. The outer side wall of each channel-shaped jamb portion bears against a jamb face in the window opening. The channel-shaped jamb portion is so formed that the outer side wall of its channel is preferably flared outwardly thereof and is flexible and resilient and bears against a jamb face on the window opening. The inner side wall of the channel-shaped jamb portion has its marginal portion bent inwardly of the window opening forming a flange projecting substantially perpendicularly with respect to said side wall. This flange is folded over upon itself providing a marginal channel overhanging the side wall which carries the flange. A sealer strip L-shaped in cross section extends along over the outer face of the inner side wall of the channel-shaped jamb portion with one leg of the sealer strip overlying said outer face and tensioned inwardly of the window opening toward a sash received within the frame. The other leg of the sealer strip is received within the flange channel being grippingly held thereby.

A meritorious feature of a window frame assembly as defined hereinabove is that the sealer strip as described in the immediately preceding paragraph has a width greater ice than the height of the inner sidewall of the channelshaped jamb portion overlaid by the strip. This greater width causes the sealer strip to project beyond the side wall overlaid thereby. This projecting portion of the sealer strip is provided with a series of vertically spaced apertures adapted to receive the latch bolt carried by the sash to maintain the sash at adjusted positions.

Another meritorious feature of the window frame assembly herein described is that the sealer strip hereinabove referred to may be perforated merely along one jamb member though complementary sealer strips are provided and such sealer strips may extend only through the bottom half of the window frame. Through the upper half of the window frame sash guide channels overlie the outer face of the inner side wall of the channel-shaped jamb portion and these guide channels are held thereon by having parts thereof received within the flange channel and grippingly held thereby.

Another meritorious feature of the within described invention is that the sill of the frame is provided with a channel-shaped sealer strip received over a part of the sill and adjustable vertically thereover to close thegap between the window frame sill and the sill of the window opening.

Other objects, advantages, and meritorious features will more fully appear from the following description, claims, and accompanying drawings wherein:

Fig. 8 is a cross sectional view taken on the same line as Fig. 4 but showing the lower window sash and the screen sash removed and showing the sealer strips 44 occupying their normal positions tensioned inwardly of the window opening.

The frame assembly comprises a pair of complementary opposed jamb assemblies indicated by the numeral 10. These jamb assemblies are connected together at the top by a header 12 and at the bottom by a sill 14. The header is channel-shaped in cross section and its inner side wall 16 has its marginal portion 18 bent inwardly toward the outer side wall as shown in Fig. 3. The sill 14 has a channel-shaped base 20 which opens downwardly as shown in Fig. 3 and is foldedv to provide an upwardly projecting inner lip 22 as shown in Fig. 3. A sealer strip 24 is folded as shown upon itself in Fig. 3 and is received over a part of the lip 22 to grippingly engage the same. This sealer strip is capable of vertical adjustment over such lip portion as shown by the solid line and dotted line illustration in Fig. 3 and is therefore adapted to close the gap between the sill proper of the window frame and the sill of the window opening identified by the numeral 26. The sill assembly also embodies an L-shaped section 28 which is secured by a screw to the base channel 29 of the sill. This L-shaped portion 30 has a lip 32 which extends upwardly and is folded inwardly upon itself as shown in Fig. 3. The other margin of this L-shaped portion is folded over upon itself so as to overlie one side wall of the base channel 20 of the sill, all as shown. in Fig. 3.

grippingly held within such flange channel.

The jamb assemblies of the frame comprise a pair of complementary channel-shaped jamb portions and channel guideways and sealer strips carried thereby. Each jamb assembly comprises a channel-shaped jamb portion indicated by the numeral 32. These jamb portions extend throughout the length of the frame. The bottoms of the channels 32 are adapted to be disposed parallel to the plane of the window opening. The outer side wall of each jamb side portion 32 is flared outwardly as shown in Figs. 4 and 5. This outer side wall is preferably flexible and resilient and bears against the jamb face of the window opening. As it bears resiliently against such jamb face it is adapted to accommodate for limited varying widths of window openings.

The inner side wall of each jamb portion is identified by the numeral 34. It is bent inwardly of the window opening forming a flange 36 which flange extends perpendicularly with respect to the side wall 34. The marginal portion 38 of this fiange is folded over upon the flange forming a flange channel overhanging the side wall all as shown in Figs. 4 and 5.

Within the upper half of the window frame inner and outer sash guide channels are mounted upon the outer faces of the inner side walls 34 of the jamb portions. In Fig. 5 two sets of side guide channels are shown. One sash guide channel is indicated as 40. Its bottom wall overlies the outer face of side wall 34. Its inner side wall overlies the flange 36 and is received within the flange channel as shown in Fig. 5. An inner sash guide channel 42 is disposed within the outer sash guide channel 40. The inner side wall of the inner sash guide channel overlies the inner side wall of the outer sash guide channel and these two inner side walls of the two guide channels are received side by side within the flange channel and grippingly held thereby. The inner sash guide channel has a width such that its outer side wall is spaced from the outer side wall of the outer sash guide channel forming a guide-way therebetween all as shown in Fig. 5. This is the condition throughout the upper half of the window frame.

Throughout the lower half of the window frame there is disposed along each jamb portion a sealer strip indicated by the numeral 44. This sealer strip is L-shaped in cross section. One leg of this L-shaped strip extends along overlying the outer face of the inner side wall 34 of the channel-faced jamb portion. This leg is normally tensioned inwardly as shown in Fig. 8 so as to bear against the edges of the sliding sash. The other leg of this sealer strip is received within the channel fold formed by the marginal portion 38 of the flange 36 being folded over as shown in Figs. 4, 5, and 8. Such other leg is This is shown in Fig. 4.

Within the window frame is shown an upper sash indicated by the letter U, a lower sash indicated by the letter L, and a screen sash indicated by the letter S. The several sash elements are vertically slidably supported between the jamb portions of the window frame. They are shown as metal sash. Generally the structure is quite similar to that shown in some of applicants earlier applications as, for example, 346,981, filed April 6, 1953.

That leg of each sealer strip 44 which overlies the side wall 34 of the jamb channel has a width substantially greater than the depth of said side wall so that the leg projects beyond the bottom of the jamb channel on the inner side of the window as shown in Figs. 4 and 8. This projecting portion of the sealer strip along one jamb of the window frame is provided with a series of vertically spaced apertures 46. The lower end .of the sealing strip is'notched as at 48 as shown in Figs. 3 and 6.

The bottom rail of the lower sash has a flange portion 5t which projects interiorly of the window opening perpendicularly to the plane of the sash. A part of this flange portion. 50 is rolled over asat 52 providing a guide support for a latch bolt 54. A screw 56 is shown as extending through the flange 50 and forming a stop for the inward movement of the latch bolt. The latch bolt is adapted to be projected outwardly toward the jamb sealer strip and through the apertures 46 formed therein. Such latch bolt is also in the lowered position of the lower sash adapted to be projected outwardly to engage the notch 43 to retain the window in the closed position.

The two sealer strips disposed on the opposed jamb portions and tensioned inwardly of the window opening as shown in Fig. 8 bear yieldingly against the edges of the sliding cash S and L mounted in the lower portion of the window assembly and prevent rattle or leakage of water or air thereabout. The latch bolt 54 is therefore engaged within an aperture 46 of a strip which is held yieldingly toward the edge of the slidable sash which carlies the latch bolt.
